I was at the track and, during the last session, the bike slipped: I was worn out and so I decided to quit: apparently, I was too tired to ride. When I was unloading the bike, I noticed that there was a little piece of rubber dangling and so I tore it off. This is the damage: I think that it was caused by a sharp stone in the dirt section of the track; I've used the tyre only two times. I will try it the next time being careful while leaning to find out if it bothers me. Since there are people who use tyres with the sides destroyed by the chain rub, I don't think that it should be a problem. Maybe the slide and the damage aren't related: slides happened other times with intact tyres. What do you think about it? EDIT: I forgot to write that the damage is on the tread of the rear tyre, on the right side.
